Test the continuity of f(x)=1÷(x-3) at x doesnot equal to 3

Good evening ,

____________________

Step-by-step explanation:

it’s a rational function then it’s continue at all real numbers except when x=3

; x≠3.

:)

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
